What is Moisture Mapping?
Moisture mapping is a crucial process in the hardwood flooring industry that involves measuring the moisture content of a subfloor to determine its readiness for the installation of hardwood flooring. It helps prevent moisture-related problems such as buckling, cupping, or splitting of the flooring.
Acceptable Moisture Levels in Hardwood Floors
The acceptable moisture level for a hardwood floor varies depending on the species of wood used, the climate, and the subfloor type. Generally, the National Wood Flooring Association (NWFA) recommends the following moisture content ranges for hardwood flooring:
- Maple, Birch, and Cherry: 6%-8%
- Oak, Ash, and Hickory: 7%-9%
- Exotic Woods (e.g., Brazilian Cherry): 9%-11%
What is an Acceptable Moisture Reading in a Hardwood Floor?
When conducting a moisture mapping test, the moisture content of a subfloor is measured using a moisture meter. An acceptable moisture reading should be within the recommended range specified by the NWFA for the type of hardwood flooring being installed.
It’s important to note that moisture levels can fluctuate over time due to changes in temperature and humidity. Therefore, it’s recommended to perform moisture mapping tests regularly, especially before installing new hardwood flooring or when moisture problems are suspected.
